Patent DE-2539786-A1 (DE)
Title: Security mounting of road vehicle number plates - uses transparent liquid filled section behind which are located numbers and which is discharged by interference
Inventor: FISCHER WINFRIED DR
IPC: G09F3/18
Filed: 1975-09-06
Abstract: A method of mounting vehicle number plates is adopted that presents great difficulty is being able to change numbers in the event of the vehicle being stolen. The vehicle registration numbers (12) are sandwiched between a solid mounting plate (9) fixed to the vehicle, and a box section (1) produced in a clear plastic material. The box section is filled with a liquid with similar optical qualities as the box material, such that the numbers are readily viewed. The box section has projecting rivet studs (8) that locate through the mounting plate. Each stud has a central bore (11) that is bridged in the middle. A cap section (8) prevents access from the rear. Any attempt to gain access to the numbers results in the rivets shearing with a consequent loss of fluid.

Title: Acetylene prepn. by combustion of natural gas - using a heat carrier prepd. from hydrogen, oxygen and opt. carbon monoxide
Inventor: SCHEVTSCHUK VASILIJ USTINOVITS
IPC: C07C2/78
Filed: 1976-03-04
Abstract: Prepn. comprises mixing natural gas and oxygen, pretreated to 630 degrees C, in a molar of 1:0.5-0.7. A heat carrier is then added, comprising the prods. of incomplete combustion of a mixt. of H2/O2 and opt. CO. The heat carrier is at 700-2400 degrees C and is added to the other mixt. in a molar of 0.001-0.4:1. The temp. of the final mixt. is 650-800 degrees C, and subsequent combustion yields an acetylene rich gas. The process is used in the petrochemical industry and is stable, wtih no premature ignition of the natural gas. Formation of by-product carbon black is reduced and yields of acetylene are improved due to the scarcity of water vapour. The heat carrier comprises H2/O2 in a molar ratio of 1:0.01-0.2 or H2/CO/O2 in a molar ratio of 1:(0.06-0.6): (0.01-0.3) at 700 degrees C. A combustion prod. was obtd. contg 8.0 vol. % of C2H2.

Title: Arc welding current supply circuit - including choke coil shunted by an ohmic resistor
Inventor: RIPKA KARL WOLFGANG DIPL ING D
IPC: B23K9/10
Filed: 1976-10-26
Abstract: The choke coil which can be subdivided pref. into a saturated and a not saturated part, lies with the latter part in parallel to a diode with series resistor and a thyristor with series resistor. This facilitates the adjustment of the voltage/current characteristic to the type of sheathed electrode used which may require a sharply drooping characteristic or a hyperbolic curve. Pref. the choke coil is divided into a saturated part and a not saturated part. The latter is shunted by a diode in series with two resistors and by a thyristor in series with two resistors. The two resistors can be bridged by switches. A firing circuit controls the thyristor as a function of the arc voltage. The saturated choke coil ensures reliable re-striking of the arc.
